For every SRPM we can find with a matching NVR (or for .0.armN
packages, matching original NVR), the "rebuilt" SRPM is compared to
the "original" one to check for differences. For SRPMs only found in
"rebuilt", packages with the same name but different versions are
listed, but not compared with. SRPMs only found in "others" are
considered new, but are still compared with.
